"That moment when you realized your maths lecturer is one of the top designer model," Azli wrote in a post comparing two photos of his teacher, Pietro Boselli: One of Boselli at the whiteboard, papers in the hand; the other of him ... not wearing very much at all.
"#OnlyatUCL," Azli hashtagged it, adding: "#Bromance."
Other students reportedly followed suit, sharing more photos of Boselli in the classroom.
According to his LinkedIn account, Boselli worked as a teaching assistant and then lecturer at UCL until June 2014. As for his modeling work, he's represented by Models1.
His Instagram says he has a PhD in engineering and is "addicted to training."
We can tell.
Don't worry: There's also video.
